Figure 9 is an enlarged fragmentary longitudinal vertical section, takensubstantially on the plane of line 9-9 of Figure 8, looking in thedirection indicated by the arrows; and

Figure 10 is a fragmentary detail view of the special slidable hingeconnection employed between each of the transversely slidable bars andthe rear side scraper blades.

Referring more in detail to the drawings, it will be noted that asubstantially U-shape supporting bracket H is secured in the forward endof the frame or chassis l2 of a motor truck or the like by bolts 3 orother appropriate means, The main portion of the bracket II is offsetdownwardly and converges toward its forward end or bight portion l4which extends at a sharp angle to the angle to the legs or sides of thebracket The bracket extends for some distance pass the forward end ofthe truckframe or chassis I2 and has a transverse bar |5 mounted on'itsforward portion and provided centrally with a pair of upstanding lugs l6supporting therein the fulcrum bolt l! for a pair of bell crank leversI8 and I9. These bell crank levers 8 and H] are employed for raisingandlowering. or tilting the substantially V-shape front shoe 20 havingthe special forward scraper blades 2| secured on its lower edge by bolts22 or the like, recesses 23 being provided in the forward face of thefront shoe 20 at its lower edge to receive the upper edges of said frontscrapers 2| so that the outer faces of the front scrapers 2| are flushwith outer face of the front shoe 20. These front scrapersZl naturallyconverge and meet at their forward ends. Both of the front scrapers 2|are curved from their upper edges to their lower edges to presentconcave 'outer faces and convex inner or rear faces. A

scraper .blade 24 is removably mounted on the forward face of each frontscraper 2| at the lower edge thereof by bolts 25 or other appropriatemeans, the scraper blades 24 being curved slightly from their upperedges to their lower edges corresponding to the curve of the frontscrapers 2|.

The scraper blades 24 furthermore, have their lower cutting edges 26bevelled or inclined rearwardly so that the scraper blades 24 may havesharp lower edges to effectively cut away ridges and the like on theroad bed. The curved or arcuate lower arm 21 of the bell crank lever I8is bifurcated and has its branches loosely connected as by means of linkconnections 28 with the rear transverse bar 29 connecting the divergingbranches of the front shoe 20, beneath the bracket The long upstandingarm 30 of the bell crank lever I8 is pivotally connected with anactuating which extends rearwardly over the engine casing. 32 of themotor truck and into the body or cab 33 thereof, a hand grip 34 beingprovided on the free rear extremity of the bar lever 3| by means ofwhich the operator may readily actuate the bar lever 3| and set the same'in adjusted position by'catching the proper rack teeth 35 on theunderface of the bar lever 3| in the plate 36 through which th bar 3|operates,

within the motor truck body or cab 33. The

lower arcuate arm 3'! of the bell' crank lever I9 is likewise looselyconnected by a link connection 58 or the like with the forwardtransverse bar 39 connecting the branches of the front shoe 20 be- -56have slidable thereon the collars low and forwardly of the bracket H.The long upstanding arm 40 of the bell crank lever l9 is pivotallyconnected to the forward lower end of the bar lever 4| for controllingthe same and which projects into the body or cab 33 of the motor truckwith an appropriate hand grip 42 on its rear end by means of which theoperator may readily actuate the bar lever 4|. This bar lever 4| alsohas rack teeth 43 on its lower face adjacent its rear end for lockingengagement with the plate 44 in the motor truck body or cab 33 andthrough which the bar lever 4| extends. It is apparent that by actuationof the bar levers 3| and 4|, the forward end or the rear end of thefront shoe 20 and parts carried thereby may be tilted as desired or byactuation of the bar levers 3| and 4| together, the front shoe 26 andparts carried thereby may be raised or lowered vertically. Duringraising and lowering of the front shoe 20 and parts carried thereby, theangular guides 45 carried on the inner face of the shoe 20 at oppositesides thereof serve to guide the shoe 20 with friction reduced to theminimum, as the angular guide bars 45 are located opposite the forwardcorners of the bracket l l.

Mounted transversely beneath the frame or chassis I2 at the centrethereof or just rearwardly of the centre, is a rear scraper supportingbar 46 having a pair of straps 47 mounted on its opposite ends andprojecting slightly from the sides of the motor truck chassis |2 andsupporting upstanding hinge pins 48 on which are mounted the hingeplates 49 of the pair of diverging rear scrapers 50, the hinge plates 49being secured on the rear or inner faces of the rear side scrapers 50and projecting from the forward ends thereof. The hinge plates 49 are ofarcuate form with collars 5| on their projecting upper and lower endsand which collars 5| are loosely mounted on the upper and lower portionsof the respective upstanding hinge pins 48. It will thus be seen thatthe rear side scrapers 56 may be adjusted vertically on the hinge pins48 and retained in their vertically adjusted position by small collars52 positioned on the hinge pins 48 below the lower collars 5| andsecured in their adjusted positions vertically of the hinge pins 48 bysecuring pins 53 or the like passed through the collars 52 and throughthe selected openings of a series of spaced openings 54 extendedtransversely through the lower portions of the upstanding hinge pins 48.The rear side scrapers 54 are straight from their upper edges to theirlower edges with scraper blades 55 secured on their lower edges andcurved outwardly therefrom with the bottom edges of said scraper blades55 bevelled on their under faces so as to present sharp lower edgeswhich will effectively cut away ridges or the like on the sides of theroad bed. Upstanding vertical hinge bars 56 are provided on the innerfaces or rear faces of the rear side scrapers 58 just forwardly of thecentre thereof. These hinge bars 5? provided at the outer ends of hingeplates 58 which are hingedly mounted on the rear faces of a pair oftransversely movable rack bars 59 sliding through guide loops 60 on asupporting plate 6| mounted transversely on the rear portion of themotor truck chassis l2, rack teeth 62 being provided on the forwardfaces of the rack bars 59 from their overlapping inner ends for thegreater portion of the length of said rack bars 59. The rack bars 5!!are operated together to force the rear side scrapers 5|) outwardly fromone another or draw them inwardly toward one another on theupstanding'hinge pins 48, by means of a'pinion 63 positioned betweensaid rack teeth 82 thereof, said pinion 63 being carried on the upperend of a stub shaft 64 rotatable through the plate 6| and through abearing 65 positioned beneath said plate 6|. A bevelled gear 88 iscarried on the lower end of the stub shaft'64 and operated by a bevelgear 61 meshing therewith and carried on one end of an operating shaft68 which in turn is carried inappropriate bearings 69- swung beneath themotor truck chassis I2, the shaft 68 extending rearwardly and projectingfrom the rear end of the chassis I2 with an actuating crank 18' on itsrear extremity. To looktheshaft 68 against unauthorized rotation andthus maintain the rear side scrapers 58 in set adjustment, a ratchetwheel H is rigidly mounted on the shaft 58 and normally engaged by adouble reversible-pawl 12 having its arms or branches directed at rightangles and the free ends 13 thereof slightly turned or bent in oppositedirections for positive looking with the teethor the ratchet wheel 1I,said double reversible pawl 12. being mounted at its centre ona fulcrummember 14 carried on the rear of the chassis I2. To reduce friction tothe minimum during adjustment of the rear side scrapers 58, a pair ofgrooved antifriction rollers or idlers 15 are mounted on the plate 61with their peripheries engaged against the outer faces of the respectiverack bars 59. The rear side scrapers 58 are brought in close to thesides of the motor truck chassis l2, inwardly of the free rear ends ofthe diverging branches of the front shoe 2!) and the front scraperblades 24 carried thereby so as to catch all snow and ice and the likecut from the surface and thrown out by the front scraper blades 24.Furthermore, the rear side scrapers 28 are of considerable length, thuspermitting proper adjustment of the same to assure cutting away ofridges'and the like from the centre of the road bed to the outer sideedges of the road or as near to the same as desired.

As the construction of the device has thus been described indetail,-b'rief reference is now had to its use and modus operandi: Thefront shoe 28 and parts carried thereby are raised and lowered or tiltedeither forwardly or rearwardly asdesired, by proper manipulation of thebar levers 3| and M by the operator while still in his position withinthe body or cab 33of the motor truck. Adjustment of the rear sidescrapers 58-and the scraper blades 55 carried thereby is accomplished,however, when the snow plow is stationary. The rear side scrapers 58 maybe readily raised or lowered on the hinge pins 48 and the collars 52secured in adjusted position below the lowermost collars thus assuringretension of the rear side scrapers 58 and blades 55 in verticallyadjusted position. The shaft 68 may be readily manipulated by the crank18 for swinging the rear side scrapers 58 outwardly and inwardly on thehinge pins 48 when the pawl 12 is thrown on its fulcrum member 14 toinoperative or non-functioning position.

In the modified form shown in Figures'fi to inclusive, the machineincludes a body 16 having side runners 11 supported along the sidesthereof by transverse beams 18 extended beneath the body 16 andconnected at their opposite ends with the inner sides of the runners 11.An additional brace bar 19 is extended across the forward portions ofthe side runners 11 outwardly of the forward end of the body 16 tofurther brace and strengthen the side runners 11. A tongue carrymg bar88 is extended across the front of the side runners I2 and rotatable inbearings 8! carried on said runners 11. .A draft tongue 82 has its rearend secured to the centre of the bar 88 and the draft tongue 82 isbraced by angularly'ex t'ended brace'bars 83 which have their rear endsturned and secured to the bar 88 by'appropriate fastening means, whiletheforward ends of the brace bars 83 are also turned and secured onopposite sides of the draft tongue 82byappropriate fastening means 85.

The forwardly converging front scraper blades '86 have their forwardends meeting and firmly fastened together and the upwardly curved frontshoe 81 is secured to the connected forward ends of the front scraperblades 86. The shoe 81 is preferably formed of a metal bent upon itselfwith the lower end 88 of the material secured beneath the connected endsof the front scraper blades 86-, while the other end 89 of the frontshoe material is extended upwardly and then bent down over the scraperblade supporting plates 98 on which the blades 86 are carried, said end89 being bent around and secured on a transverse pin 89a extendingthrough the plates 98. In order that the front scraper blades 86 may bereadily raised and lowered or tilted to the desired incline, the plates98 are loosely connected to the forward ends of the side runners 11 byslide hinges 9i. These plates 98 are connected-by a transverseconnecting bar 92, forwardly of the body 16 and the side runners 11 anda pair of rearwardly converging bar levers 93 have their forward endshinged to the bar 92, near the ends of the latter. These bar levers 93extend over and rock on the transverse-bar 19, beneath the bar 88. Owingto the main portion of the bar 88 being raised or offset upwardly, thebar levers 93 may be operated without interference by the bar 88.

Each side runner 11 has at its centre a longitudinally elongatedvertical slot 94 which has its forward and rear walls inclined so thatthe top of the slots 94 are longer than the bottom thereof. Working ineach slot 94 is a wide knife 95 having its lower end 96 bevelled andslightly turned forward. Each knife 95 is adjustable vertically withinits respective slot 94 and is' slidable through a loop guide 91 carriedon the inwardly offset end 99 of a U-plate 98 supported in the slot 94by means of a bolt I88 extended transversely through the centre of theslotted portion of the side runner 11, near the upper edge thereof. Theknives 95are each raised and lowered in their respective slots 94 andthus ad justed to the proper height within the side runners 11, by meansof a slightly curved finger I8I provided on the bevelled'forward end I82of a Each lever lever I83, by bifurcating the same. I83 is carried on afulcrumed member I84 extended transversely through an upstanding bracketI85 on the side runner 11 for which the knife 95 is provided. Each leverI83 is then extended upwardly and carries a conventional spring latchI86 for automatic locking engagement with the segmental rack I81positioned adjacent the lever I83, so that. the latter may be readilylocked in adjusted position. When either lever I83 is to be re-adjustedfor raising or lowering the knife 95 controlled thereby, the lever 183may be readily released from the segmental rack I81 by theconventionalreleasing finger I88 provided for this purpose on the lever I83. It

WiIL'thBIBfOIB, be apparent that the knives 95 may be independentlyadjusted and as the levers with the planes parallel to one another.

other bar H3 slides.

I 03 converge towardone another, as they are extended upwardly andrearwardly, they may be readily operated by the attendant on the body16, the same as the levers 93 which are forwardly of the levers I63.Hoods I89 are positioned over the slots 94 and extended outwardly overthe sides of the body 16, to discharge to the sides of the machine, thematerial cut by the blades and rising in the slots 94.

The pair of rear side scraper blades H0 are carried on the guide wingsIII which are hinged at their forward ends to the outer faces of theside runners i1, rearwardly of the centres of the latter, by appropriatehinges H2. The wings H i diverge real-wardly and the transverselysliding supporting bars H3 for the wings III have their outer endsconnected to the inner faces of the wings ill at about the centrethereof, by the loose hinges I M, straps l I la of which are hinged onthe respective bars H3. Supporting bars H3 slide transversely across therear portion of the sleigh body 18 with their inner ends overlapping,owing to positioning of one of the bars H3 in a plane slightly forwardlyof the other Each of the bars H3 carries a loop guide H5 projectinglaterally therefrom and through which the Both of the bars H3, at theiroverlapped portions are adjustable through a larger loop guide H6 formedby offsetting upwardly a portion of the strap H1 secured longitudinallyon the body E6, so that the bars H3 may be readily adjusted transverselyof the body 76 to regulate independently the angle of each of theseWings Hi and the rear scraper blade H0 carried thereby. A set screw H8or other means is employed for securing the bars H3 in adjusted positionin the loop I [6.

As the construction of this modified form has now been fully described,brief reference is now had to the use and modus operandi thereof: It isto be noted that the snow, plow could be drawn by any appropriate powerconnected with the tongue 82. The body 76 of the machine is firmlysupported on the side runners T! which ride on the road bed and permitadjustment of the front scraper blades 86; the knives 35 and the rearscraper blades H5, independently, by the attendant on the body '55. Therear scraper blades H8 continue the scraping work of the forward frontscraper blades 86 and serve to throw the loosened material to eitherside of the road bed.

At the same time, the knives 95 may be employed for cutting away ridgesor projections on the road surface such as the side walls of ruts,formed by the wheels of motor vehicles, wagons or the like, so as topresent a smooth surface the entire width of the road bed. These knives95 may be readily adjusted to correspond or independently of oneanother, by separate adjustments of the levers I93 for the respectiveknives 95. All of the adjustments may be readily effected by theattendant while positioned on the body 16 of the snow plow and theadjustment may be made without interferring with proper functioning ofthe side runners T! or the connection of the snow plow with its draftmeans.

From the foregoing description taken in connection with the accompanyingdrawings, it will be manifest that'a combination snow plow is providedthat will fulfill all thenecessary requirements of such a device, but asmany changes could be made in the above description, and many apparentlywidely different embodiments of my invention'may be constructed withinthe scope of the appended claims without departing from the spirit orscope thereof, it is intended that all matters contained in the saidaccompanying specification and drawings, shall be interpreted asillustrative and not in a limitative or restrictive sense.
